Robust Statistical Pixel Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Robust statistical methods are employed to reduce the noise in Monte Carlo ray tracing. Through the use of resampling, the sample mean distribution is determined for each pixel. Because this distribution is uni-modal and ...
Real-Time Subspace Integration for Example-Based Elastic Material
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Example-based material allows simulating complex material behaviors in an art-directed way. This paper presents a method for fast subspace integration for example-based elastic material, which is suitable for real-time ...
Database-Assisted Object Retrieval for Real-Time 3D Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In recent years, real-time 3D scanning technology has developed significantly and is now able to capture large environments with considerable accuracy. Unfortunately, the reconstructed geometry still suffers from incompleteness, ...
VDub: Modifying Face Video of Actors for Plausible Visual Alignment to a Dubbed Audio Track
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In many countries, foreign movies and TV productions are dubbed, i.e., the original voice of an actor is replaced with a translation that is spoken by a dubbing actor in the country's own language. Dubbing is a complex ...
Optimal Spline Approximation via l0-Minimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Splines are part of the standard toolbox for the approximation of functions and curves in Rd. Still, the problem of finding the spline that best approximates an input function or curve is ill-posed, since in general this ...
High-Order Recursive Filtering of Non-Uniformly Sampled Signals for Image and Video Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a discrete-time mathematical formulation for applying recursive digital filters to non-uniformly sampled signals. Our solution presents several desirable features: it preserves the stability of the original ...
IlluminationCut
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a novel algorithm, IlluminationCut, for rendering images using the many-lights framework. It handles any light source that can be approximated with virtual point lights (VPLs) as well as highly glossy materials. ...
Rich-VPLs for Improving the Versatility of Many-Light Methods
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Many-light methods approximate the light transport in a scene by computing the direct illumination from many virtual point light sources (VPLs), and render low-noise images covering a wide range of performance and quality ...
Distilled Collections from Textual Image Queries
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a distillation algorithm which operates on a large, unstructured, and noisy collection of internet images returned from an online object query. We introduce the notion of a distilled set, which is a clean, ...
CHC+RT: Coherent Hierarchical Culling for Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We propose a new technique for in-core and out-of-core GPU ray tracing using a generalization of hierarchical occlusion culling in the style of the CHC++ method. Our method exploits the rasterization pipeline and hardware ...
